Analysis

This article from Zenn AI questions the increasingly common practice of including personas in system prompts for generative AI. It raises concerns about the potential for these personas to create a "black box" effect, making the AI's behavior less transparent and harder to understand. The author argues that while personas might seem helpful, they could be sacrificing reproducibility and explainability. The article promises to explore the pros and cons of persona design and offer alternative approaches more suitable for practical applications. The core argument is a valid concern for those seeking reliable and predictable AI behavior.
